Am I selfish to only want one kid?

We have a beautiful little girl who is almost 5 month old. She is the light of my life and I never knew I could love someone this much until I had her.Most of my life I always assumed I would have 2 kids, probably because I grew up with a brother. I have so many fond memories of growing up with him. Sadly when he was 29 and I was 25 he died. Although I am still so grateful I had all those years with him.Fast forward to the present, I am 29 and have my beautiful girl. And honestly I don't want any more kids. I am so content and happy with her. She is honestly the easiest baby and such a joy.Before having her I felt such a strong desire for children, but I can honestly say she has filled that need for me.My husband and I have had many talks about whether or not we should have another one, he said something that hits the nail on the head. "I don't really want another but, but i feel like I should." Which is exactly how I feel. At this point my only real reason for having a second kid would be to give dd a sibling, and I'm not sure that's a good enough reason.I also have kind of a morbid reason for wanting a second, and that's what if something ever happened to dd. Not that having another kid would make it any less horrible, but it would give you a reason to keep going. But making decisions out of fear and 'what-ifs' is no way to live.Many of my friends have told me I have lots of time to decide, but honestly I don't feel like i do. My husband and I both agree if we were to have another we would want them close in age (2 years or less). I guess it just boils down to the fact that i am so happy as a family of 3. She fits into our lives so perfectly, why fix something that isn't broken.I guess i'm just looking for reassurance. Parents of only children, do you regret not having more? Or wish that you could have? via /r/Parenting http://ift.tt/2ww94RQ
